6 Claims. (01. 155-447) The present invention is an improvement in folding chairs of the kind disclosed in my Patent No. 1,604,108, dated October 26, 1926. i i i It is an object'of the invention to provide such chairs with side arms. so COIlIlSQtBdtOYthB chair back as to be automatically brought to side arm position concurrently withthe unfolding of the chair from a collapsed to an open usable position. Also it is an object to provide means acting through .the arms .to limit the opening movement of and to brace the back in open position.

Importantly, it is an object to provide a chair of this class in which all of'its parts areself effective; that is, it is not necessary to manually I connect or disconnect any of the several elements when either folding or unfolding the chair all parts automatically taking their intended positions, in either adjustment, when the chair-is opened or closed. In other words there-areno 1 parts which must be hooked or unhooked or fastened or loosened in any way when the chair is to be set up or collapsed. V

The invention consists in certain advancements in this art as set forth in the ensuing disclosure and having, with the above, additional objects and advantages as hereinafter developed, and whose construction, combination and details of means, and-the manner of operation-will be made manifest in the description of the herewith illustrative embodiment; it being understood that modifications, variations and adaptations may be resorted to within the scope, principle and spirit of the invention as it is more directly claimed hereinafter.

Figure l is aperspective of the unfolded chair.

Figure 2 is a front elevation of the unfolded chair,

Figure 3 is a vertical cross-section thereof; the back not being fully opened.

Figure 4 is a back plan of the collapsed chair,

Figure 5 is a side View thereof.

Figure 6 is a sectional detail showing the fas tening of the pliable seat of the chair. 7

The chair comprises a pliable seat 2, of heavy fabric or othersuitable material, and its front portion is attached to a front cross bar 3, having a half-round top, which is secured on the end faces 4 of inner, side legs 55, while the rear portion is connected to a cross bar 6 which is morticed into the lower corner of the upper, rear ends of outer side legs 66.

The side legs are crossed and joined in side pairs by individual coaxial pivots 7-7, and are thus axleless, this being a lower cost device than posts lie flat against the relative outer legs.

wherea long axle pivot is'used. The seat 2 forms. a. substantial sole means connecting the upper ends of the legsand limiting opening action thereof in use.

The lower-front ends of the legs are tied by a cross-piece 8 and the lower rear ends by a cross-- rod 9. 1

A back structure comprises a pairof posts 1010 whose lower ends are attached by suitable hinges l1-l1to.the upper, rear corners of the legs in sucha mannerthat'the opened back post lower endfaces 12 will abut firmly against the opposed end-facesl3- of the legs, 6-.6. Side arms l-e-l are pivoted at 15 onthe outer faces of the posts 10 -10 and are hinged at 16 on the upper ends-of ends are lapped on the sides of the rear ends of legs, 66,and securedibypivots 18., Thus when the back is opened up the :armscome to usable positioniautomatically.; i g, p

An important device of the invention resides in a pair of stop and brace links 19-19 whose upper ends are pivoted at 20 against the inner facesofthe brackets 17 and whose lower portions have long slots 21 receiving the pivots 7-7 ofrespective pairs of legs. It will be seen that as the arms open with the back the links 19 will be pulled up: until the lost slot motion is taken up and then the links become, with the brackets, 17 and with the abutted faces 12-13, means to brace the open back against rearward pressure of the occupants back.

It is understood that all parts may be made of any desired size and material, and of any preferred finish, and that either screws or rivets may be employed at will in the manufacture of the chair, in securing the several elements together. V

The seat is shown as both tacked at'22 on one face, and stapled at 23 to the bottom of the cross bar in Fig. 6. i 7

Where desired washers 24 are introduced under or between the working parts and their pivots.

" To unfold the collapsed chair from its position of Fig. 5, the back 10 is swung forward and upward to the position of Fig. 3, and then the inner pair of legs to the top portion of which the seat is attached is pulledforward to the limit, Fig. 3. To close the chair the procedure is just reverse, that is, the seat is collapsed by the folding up of the legs and then the back is swung down over the folded legs. It will be seen that the several legs all fold into one plane and that the back,

The

side arms and their brackets, when foldedlie l5 brackets 17 17, Whose lower within the confines of the folded back and legs; the whole making a very compact collapsed chair.

It is found by actual construction of the parts of Wood of suitable hardness and plane design and smallest practicable dimensions that an extremely substantial and durable chair is produced, and that, at a very low cost.

What is claimed is:

1. A folding chair havingv braced, outer and inner legs crossing each other and pivoted together and all connected at thetop ends by a seat, a back having side posts pivotally connected to the upper ends of the outer legs, a pair of arms pivotally connected to the side posts, a pair of brackets pivotally connected to the arms and to 1 the outer legs, and a pair of brace links pivotally connected to the brackets of the arms and having slotted ends pivotally and slidably connected to the leg system.

2. A folding chair having braced, outer and inner legs crossingeach other andpivoted together and all connected at the top'ends by a seat, a back having side posts pivotally connected to the upper ends of the outer legs, a pair of arms pivotally connected to the side posts, a pair of brackets pivotally connected to the arms and to the outer legs, and a pair of brace links pivotally connected to the brackets ofv the arms and slidably connected to the leg system. 1

3. A folding chair having braced, outer-and inner legs crossing each other and pivoted together and all connected at the top ends by a seat, a back having side posts pivotally'connected to the upper ends of the outer legs, a pair of arms pivotally connected to the side posts, a pair of brackets pivotally connected to the arms and to:

the outer legs, and a pair of brace links pivotally connected to the brackets of the arms, means pro-i viding a lost motion connection between said arms and the leg system and a pliable seat conto the legs and the connected to said arms and to said legs to limit opening movement of and to brace the unfolded back; the links being connected to respective arm and leg parts and the brackets being connected to respective arms and pivots of the side legs.

5. A folding chair having braced, outer and inner side legs pivoted in side pairs, at back structure pivoted on the upper rear ends of said legs whose tops are connected by a seat, side arms pivotally connected to said back, and means connected to said arms'and to said legs to limit opening movement of and to brace the unfolded back, said means including foldable bracket and link devices connecting respective arms to respective side leg pairs; the brackets connecting the arms linksconnecting the brackets to leg pivots.

' 6. A folding chair having an axleless set of side crossed braced pairs of crossed legs, each pair having its own pivot connection, a back structure pivoted on the upper, rear ends of the legs, side arms pivoted on the said back, brackets pivoted on said arms and on said upper rear ends of the legs, a seat part connecting the tops ofthe legs from front to back and means connecting said arms'to the pairs of legs and including side links pivoted on said brackets and having slotted ends working on the pivots which connect the legs inpairs.
